Intro to Palaeontology - Thursday, 1st Period
“This week we’re going to be exploring the last era of the Age of the Dinosaurs and that is the Cretaceous Period,” Cutter began that week’s lecture, handing out his normal stack of notes. “As we did last week, we’ll start with our reports on the animals from the Jurassic Period that I asked you to prepare last week,”
Once the last report had been presened, Cutter resumed his lecture.
“The Cretaceous Period also happens to be the longest of the previous periods and covers a span of 79 million years, lasting from 145 million years to 66 million years ago,” there was a pause, “the Cretaceous Period is known for being much warmer in terms of climate - specifically warmer ocean currents, unfrozen poles and relatively higher levels of CO2 emissions,” he explained.
“This is the era where you have some of the more well known dinosaurs such as the Tyrannasaurus Rex, Velociraptor and the Triceratops,”
“I mentioned at the start of the lecture that this period is the last era of the Mesozoic Era,” Cutter continued, “so what happened to the dinosaurs? Sixty Six million years ago an asteroid caused the chain of events that led to the mass extinction of the dinosaurs, with the exception of the avian dinosaurs, since the avian dinosaurs lineage now survives today in modern bird species,” he paused, “and this is known as the Cretaceous-Paleonge Extinction Event, which also happens to be the last of the five major extinction event that the Earth has experienced - we will be covering these events later on in the semester but we’ve briefly talked about two of them during the last couple of weeks covering the Mesozoic Era - the Permian-Triassic Extinction Event and the Cretaceous-Paleonge Extinction Event ”
“Next week we will be moving on to a different topic but I would like you to write a report on an animal that lived in the Cretaceous period to present next week,”
